WlRE-S TRETCHER.

SPECIFICATION forming part of Letters Patent No. 286,302, dated October9, 1883.

Application filed June s, was. (NomodcL) durability, inexpensiveness,and general effi ciency.

In the drawings, Figure 1 is a perspective view of my improvedwire-stretcher in position for operation. Fig. 2 is a verticallongitudinal sectional view of the same. Fig. 3is a detail perspectiveview of the stretchinglever.

Referring to the drawings, A designates the main frame of the device,which comprises four main posts, B, that converge upwardly H is thestretching-lever, which is provided near its lower end with aperforation, I, in

which is adjustable a transverse fulcrum-bar, J, by'means of aset-screw, K, as shown. This fulcrum-bar operates between the bars B ofthe frame, and is adjustable in the hooks G, the pairs of whichcorrespond in heightto the different strands of the fence, so that thefulcrum of the lever can be adjusted to about the same horizontal planeas the strand of the fence that is being stretched. .In one side of thelever is formed a recess that provides an upwardly and rearwardlybeveled shoulder, L, against which the wire, whichis designated by theletter M, is clampedby the corresponding beveled end, N, of a plate orlever, O, that is pivoted to the lever H in the said recess.

These beveled edges L and N are preferably serrated, as shown, tosecureabetter hold upon the wire, and will tightly secure the latterwhile the lever H is being brought down in the direction of the arrow,Fig. l, to stretch the wire. By reason of the bevel being upward andrearward, the plate 0 is clamped tighter against the shoulder L, as thestrain caused by stretching the wire is greater. A drum, 1?. isjournaledbetween the rear beams, B B, of the frame, to carry the wireand pay it out as the stretcher is moved forward. The

shaft of the drum is preferably provided with a crank, Q, as shown.

The operation and advantages of my invention will be readily understoodand appreciated. It is very simple and can be conveir iently operated.

I claim as my invention- The combination of the portable frame,comprising the upwardly and inwardly convergent bars, carrying thevertical series of bearing hooks or loops, and the bottom braces,forming transportation-handles, the drum journaled at the rear end ofthe frame, the stretching-lever having the recess and shoulder and theclamping plate or lever and formed with the fulerunr opening, and thefulcrum-bar, adjustable in the said opening by means of a set-screw, as'

and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in pres-' ence of two witnesses.

ALEXANDER HILL.
